Description

The authors propose the powered roof support of the stepped type. Such design ensures safe and efficient mining, as well as complete extraction of coal from thick seams with coal discharge to the rear armored face conveyor. The paper describes physical simulation and numerical modeling of two-stage top coal discharge. (paper)
